Voice is a native channel: Rexenda's AI agents answer and place calls on Rexenda phone numbers and on WhatsApp, use tools during the call and leave the transcript and summary in the inbox.
A Trengo alternative with a free plan, AI agents and built-in voice
Trengo is a European omnichannel inbox priced per workspace, with AI billed per conversation and voice as a paid add-on. Rexenda takes a different approach: AI agents that sell and support on WhatsApp, other chat channels, email and phone calls, with a CRM, quotes and payments in the same place.

Why teams look for a Trengo alternative
Entry price and billing unit. Trengo's plans are priced per workspace, from €299 a month on annual billing (€349 month to month) with 10 users and 500 conversations a month included; extra conversations are sold in packs of 100.
AI paid per conversation. Beyond a small monthly allowance, each conversation handled with Trengo's AI costs €0.25 to €0.30, deducted from a prepaid balance, and its AI agent on calls is billed per minute while in beta.
No built-in sales CRM. Trengo offers contact profiles, labels and custom fields, and connects to CRMs such as HubSpot, Salesforce and Pipedrive through integrations, so pipelines and deals live in another tool.
What Rexenda does differently
AI usage comes from monthly credits included in every plan, not a per-conversation fee: one AI reply is one credit, a minute of AI voice call is twelve, and extra packs are available.
A CRM with contacts and a sales pipeline, plus quotes with an acceptance link, card payment links paid into your own Stripe account and, in Mexico, CFDI e-invoices.
Start on a free plan with no time limit and no credit card, then pay monthly or yearly when you upgrade, with prices shown in USD, MXN or EUR.
How to switch
Export your contacts from Trengo as a CSV file and import them into Rexenda: you map the columns, review before importing and can undo the import. Connect WhatsApp in minutes with Meta's Embedded Signup; if the number is connected to Trengo, disconnect it there first, since a number can be linked to only one platform at a time. Then connect your email inboxes, Instagram and Messenger, and rebuild the rules and flows you rely on in Rexenda's visual flow builder.
When Trengo may still be the right choice
Staying with Trengo makes sense if your team is in Europe and prefers EUR pricing, relies on its hospitality and e-commerce integrations such as Booking.com, Airbnb or Shopify, or already runs its sales pipeline in HubSpot, Salesforce or Pipedrive and only needs a shared inbox on top.
Questions
How is Rexenda different from Trengo?
Trengo is a shared omnichannel inbox priced per workspace, with AI charged per conversation and voice as an add-on. Rexenda is built around AI agents that work on chat channels, email and phone calls, includes a CRM with quotes and payment links, and pays for AI with monthly credits included in each plan. Rexenda also has a free plan with no time limit, while Trengo starts with a 7-day trial.
Can I switch from Trengo without changing my WhatsApp number?
Yes. Disconnect the number in Trengo, then connect it to Rexenda with Meta's Embedded Signup; your customers keep writing to the same number. Resubmit the message templates you use, and bring your contacts through a CSV import with column mapping, review and undo.
Can I bring my Trengo conversation history?
Not directly. Rexenda imports contacts from CSV files, but it has no importer for Trengo conversations, so past threads stay in your Trengo account. Plan the switch for a quiet moment, and finish or hand over open conversations before you move the number.
